Normal cervical cells in a Pap smear. In the conventional Pap smear, the collected cells are smeared on a microscope slide, and a fixative is applied. The slide is evaluated in a pathology lab to identify cellular abnormalities. Accuracy of conventional cytology report: [10] sensitivity: 55% to 88%; specificity: 71% to 94%
The Papanicolaou test (abbreviated as Pap test, also known as Pap smear (AE), [1] cervical smear (BE), cervical screening (BE), [2] or smear test (BE)) is a method of cervical screening used to detect potentially precancerous and cancerous processes in the cervix (opening of the uterus or womb) or, more rarely, anus (in both men and women).

Papanicolaou stain (also Papanicolaou's stain and Pap stain) is a multichromatic (multicolored) cytological staining technique developed by George Papanicolaou in 1942. [ 1 ] [ 2 ] [ 3 ] The Papanicolaou stain is one of the most widely used stains in cytology , [ 1 ] where it is used to aid pathologists in making a diagnosis.
Per the expert, there’s no one-size-fits-all answer to this—namely because how often women should get a pap smear depends on their age and gynecologic history.
In Georgios' own words: “The first observation of cancer cells in the smear of the uterine cervix gave me one of the greatest thrills I ever experienced during my scientific career.” [9] The Pap test is still widely used as a means of early cancer detection and is estimated to have reduced fatalities caused by cancer of the reproductive ...
Brushes used to collect samples for cytology. Liquid-based cytology is a method of preparing samples for examination in cytopathology.The sample is collected, normally by a small brush, in the same way as for a conventional smear test, but rather than the smear being transferred directly to a microscope slide, the sample is deposited into a small bottle of preservative liquid.

The Ayre spatula is a device used to collect Pap smear. It is a wooden spatula with U-shaped openings on one side and a flat surface on another. [1] The broad end is for vaginal sample collection and the narrow end is for cervical sample collection. It is rotated 360 degrees in the vagina to obtain the cells to be sent for Pap smear examination.
